i have been thinking of using sorbs instead of spamhaus because sorbs allows
sites with upto 100k user to connect to them but with spamhaus u are limited to
100users max. Sorbs has a detection rate of about 68% and i was thinking of
beefing our spam wall with grey listing.
Do u have any suggestions about this?
